[rabbitmq-discuss] limits.conf not working...

[Gonzalo Fernandez]

Hello all,

I have been doing some research over the past weeks unsuccessfully.

Let me explain, now I have an Ubuntu 2.6.32-38-server machine with rabbitmq
2.8.1 running.
As you can see below the file descriptor is just is 1024 (924 at the
moment) and the socket limit is 829.

Well, I also had rabbitmq running before in another machine (OLD machine
from now on), same files, same code, the only difference was rabbit's
version, 2.7.1

On the OLD machine I managed to increase these limits (file and socket) by
editting the /etc/security/limits.conf file as shown:

*rabbitmq  soft  nofile 10011*
*rabbitmq  hard  nofile 65000*

And adding the following line to *
/etc/pam.d/common-session{,-noninteractive}*
*session required pam_limits.so*
*
*
*
*
This worked fine, and on the rabbit management plugin I could see these
changes:

When I tried to do the same on the NEW machine it seems like it is not
working fine.

When I execute *ulimit -n* with rabbitmq user I get the same value
as*limits.conf
*, but in the management site......

*rabbit at test: ulimit -n *
10011

Any thoughts?

I can't find the error..... Could it be the version?


Thanks for your response in advance.
